IMPROVEMENT IN LUBRICATING-OIL CUPS.

vSpecification forming part of Letters Patent No. 18,863, dated December 15, 1857.

`To all whom it may concern:v

Be it known that I, ENOCHN. ROLAND, ofthe city and county of Baltimore and State o f Maryland, have invented an Improved Oil- Cup for Steam-Engines; and I do hereby declarerthat the following is a full and exact description thereof, reference being had to the accompanying drawings making a part of this specication.

. lFigure l is a top view of said oil-cup; and' Figs. 2, 3, and 4 vertical sections of the same, representing the respective parts thereof in different positions.

Similar letters indicate like parts in each drawing.

` 'IIhe body of my improved voil-cup is composed of the sections A B, which are united nel or funnel-shaped cup, and a screw-thread is formed within an enlarged portion of.` the aperture in saidneck. A cross-balfhywhich: is combined with the lower extremity of the said section A, has a vertical screw-aperture `f' formed within the center ofthe same.=

The perforated screw-neck g, scends from the lower extremity of thesection `B of the aforesaid oil-cup, enables the said cup to be conveniently combined with a steam-engine.

One, two, or more vertical grooves are formed in the sides ofthe screw portion of the aperture within the neck of the section A of my improved oil-cup, which groove or grooves may descend nearly to the shoulder at the bottom of the screw portion of the aperture in said neck.

The screw-valve b lits accurately into the' screw-aperture within the neck A of my improved oil-cup, and the screw-shank ot the valve d works accurately within a 'central screw-aperture ir; the said valve b, and lalso within the screw-aperture in the cross-bar h. The lower extremity of the valve b is o) such a shape that it fits accurately to the shoulder 1I when it is turned down to its lowl1 .1 v, est position, and the face of the valve d is of such a shape that it perfectly closes the aperture in the neck g, which descends from the lower section B of theoil-cup.

The usual position ofthe valves of my improved oilcup is represented by Fig. 2. The said oil-cup having been combined with a steam-engine, the piston ofsaid vengine is supplied with oil'in the following. manner, viz: vThe valve b-mustrst be unscrewed to such a degree as to bring its seat above the lower ends of the grooves f f, as shown in Fig. 4, and then oil or melted tallowipoured into the funn el e will iow freely nf'e the interior of the oil-cup. As soon as a sulicient vquantity of oil or tallow has beeaconveyed into the body of Athe-oil-cup the valveib mustbe screwed down again so iirmly as to cut off .all communication between the interior of the oil-cup and the funnel e; then, by elevatf ing the valve d, as shown in Fig'. V3, the oil or tallow will pass .freely into the cylinder of the steam-engine without. allowing the steam to vescape from said engine, wlth the exceptlon' of the small quantity which'will pass into the body of the oil-cup. Before the oil-cupV is again charged with oil the valve d must'be again screwed down to the/position represented in Fig. .4.

` The valve b's operatedgby means ofthe crank j, and the valve a is operated by means vof the crank' 1c..

Cold tallowmay be placed Within the funnel e, for the ,purpose of being melted preparatory to its being conveyed into thebody .of -the'oilLcup and thence into the vcylinder of the steam-engine.

Having thus-fully described the construc-f tion and operation of my improved oil-cupv for steam-engines, what I claim therein as new, and desire to secure by Letters Patent, is

` The peculiar combination of the screwlvalves b d'with each other, and .with the fun nel, neck, andother portions of said oil-cup, substantially as hereinset forth.l

The above specification of my new and improved ol-cup signed this Sth day ofSeptcm bel-,1857.
